Karl Philipp:

Two more suggestions:

5. Examine the file formats in which your work is saved to disk, and write programs to make the files generic to be checked in and particularized to a developer's configuration or to a deployment configuration after you check them out. Ask the vendor to help with this. It might well be illegal to do this in the US, but you're not blessed with out Digital Millenium Copyright Act.

6. Have a heart-to-heart talk with a representative of Vitria about how they can claim to be selling an enterprise development tool that doesn't scale past a single developer. Maybe there's a way of using the tool that you've overlooked, or maybe the vendor is in desperate need of a wakeup call.
