If you feel like donating goods or money for the work the developers are doing, then we're happy to confirm that this is indeed possible. Of course we'd really like to have you working with us on the system and become a contributor, but if you're feeling generous we won't stop you either.
The Free Software Foundation is the GNU project's principal organizational sponsor. Donations to the FSF are tax deducible. However, they can't accept donations addressed directly to/specifically for the GNU Hurd project.
Hey, I have more money than time or programming skills, and I'd like to help GNU Hurd development specifically -- how can we arrange for this, where can I donate money for GNU Hurd development?
If you're dwelling on such thoughts, here is the answer; here you can donate money for GNU Hurd development.
As its principal idea, FOSS Factory, means to serve as a hub and organizational platform for connecting Free/Open Source Software developers with monetary sponsors. From http://www.fossfactory.org/aboutus.php:
FOSS Factory's mission is to accelerate the advancement of free/open source software by helping people collaborate on the design, funding, and development of innovative software ideas. All software solutions produced using our system are released under free/open source licenses. Our unique model brings the best of innovators from both the entrepreneurial and FOSS worlds together to solve real world problems using the mass resources of the FOSS community.
In very general words, their modus operandi is that the community (including the monetary sponsors) works together with the developers on splitting up tasks into suitable and assessable sub-projects as necessary, and then act as the reviewing instance, deciding on such sub-projects' success (and payment, successively). For more details see their System Overview.
For now, we can assume that the amount of money to be made by working on a GNU Hurd task in this framework is likely to be a symbolic amount only, rather than being representative for the real effort that needs to be invested. Software development is expensive, mostly due to the amount of time that is needed for completing any non-trivial task. Instead, these bounties should be regarded as an attraction/reward, perhaps also simply as a motivation for a developer to focus on one specific problem, and bringing it to completion.
In principle, any Hurd-related development task is applicable (for example, from the GSoC project ideas, or from the open issues list), but it is of course recommendable to match sponsors' ideas with those of the developers and maintainers. For this, if you want to sponsor a project, but don't know which one to choose, or if you want to work on a bounty that is not yet listed on the site, we suggest that you talk to us first, either publically on the bug-hurd mailing list or privately on email@example.com, if you prefer.

Another possibility is to meet with the Hurd developers at a meeting and buy them a pizza or beer or both or similar.
