I just received a long email from IS. To quote a small portion:

"On March 1st 2010, Interprise Software Solutions Inc. was acquired by a group of private investors from the Taylor Corporation."

"Gary Harrison, the original Founder of Interprise Solutions, will be returning to daily operations as the V.P. of Product Development after working for the company as a consultant."

It goes on to list the improvements in support and feature plans for new versions.

Maybe there is a much desired resuscitation in process here. This appears to be real movement. The website has finally been updated a bit and the email promises much more for the users there. Time will tell.
