what could an developer do to gain sponsorship for his application

supposing an open source application wanted to become sponsored by a company so that their application development was supported.

what are the options?
these are things which some websites do, the right level of advertising may be great (like allowing short text adverts with context to what the app is doing)


fixed logo on program


sponsor website link


splash screen


popup dialog on closing


you could even create a whole new variant application fully branded to the company.


what extra chances are there for a sponsor to interact with the user?
outside the application itself, there are other chances for a sponsor message to be available?

popup after app installation
sponsor gains facetime after an application is installed
must be able to detect an interactive installation and NOT install anything for an automated console installation.

custom application sections
you could add new functionality in an application for the sponsored elements

popup splash after bootup
when the desktop starts have a small popup window with link to website etc
popups are generally undesired

bootup experience
include a custom fully rendered short bootup video
(though must be opt in at installation firstrun phase)
i think it would have to be eyecatching and short, people should be proud of their open software on their device.

what other things are there you could offer a sponsor?

which of these would you as a user be comfortable with?

which are unacceptable, which would force you to uninstall an application, which would allow you to show how proud of the applications you are?

this is a brainstorm, but i cant work out how to discuss all that, someone might want to make one after reading this
