I'm very intrigued in what you guys are offering... I just saw your site from Digg, and yes... I have Dugg the story.
So Here's my list of software that would send you guys through the roof (Make you very popular if you offered it for free)
FruityLoops v6.0

Music is created by recording and mixing audio and/or MIDI data together to create a song, which can then be saved to the program's native .FLP (Fruity Loops Project) format. Songs can be exported to a Microsoft WAV or MPEG-3 file compatible with most media players.

Bullet Candy

Description: Bullet Candy's game mechanic is inspired by Williams classic Robotron, vertical shooters such as Treasure's Ikaruga and Capcom's Gigawing, and Jeff Minter's awesome Llamatron and Tempest 2000. Huge particle explosions, masses of enemy bullets, and beautiful feedback effects combined with power-ups, score multipliers, collectable friendly ships, laser upgrades and un-lockable bonus games all add up to make a great gameplay experience
I have a few more idea's for you but those are some of the most wanted products on the internet... at least in my opinion.
Have a great day!
