use Perl

In an effort to convince more companies to sponsor Perl development and to help the various Perl events to raise money for themselves I'd like to create a public list of companies that are sponsoring Perl development. This is also a good way to thank them (again) for their sponsorship.

So far and after a quick search I found the following:

1. There are individuals and companies sponsoring Perl via the The Perl Foundation
   They are listed on the Fund Drive Status page.
2. There are companies sponsoring YAPCs and the Perl Workshops (e.g. The German Perl Workshops) directly. These companies are usually listed on the web sites of the respective conferences.
3. Stas Bekman setup a site about companies sponsoring mod_perl development but I think it was not further developed.
4. Other companies directly sponsoring Perl projects like
   Fotango sponsoring Arthur (sky) Bergman in the Ponie development

Now I need your help!
While I'd be glad to receive further links to sites listing other sponsors like in 1) and 2) my effort is to concentrate on 4) and maybe on 3) if Stas has no time to collect more information.

So please let me know about other such sponsorships and the details about them.
