How can the corporations that use TWiki help TWiki grow?

TWiki has many high-profile CorporateInstallations. While I want to encourage as many public declarations of TWiki's use as possible I'd also like to see if we can get various types of support from those companies.

Corporate contributions can take many forms. While the obvious one is in direct sponsorships and sponsorship of development of features, I'd like to brainstorm what the options are and what the sense of acceptability is.
