Well, this is certainly curious. Over on the Instantiations site, it looks like they've done away with the non-commercial download of VA. Have a look at the license agreement terms:

EVALUATION. Instantiations grants you a nonexclusive, nontransferable license to use the Software. You may 1) use the Software only for internal evaluation, testing or demonstration purposes, on a trial or "try-and-buy" basis and 2) make and install a reasonable number of copies of the Software in support of such use. The terms of this license apply to each copy you make. You will reproduce the copyright notice and any other legends of ownership on each copy, or partial copy, of the Software. You will 1) maintain a record of all copies of the Software and 2) ensure that anyone who uses the Software does so only for your authorized use and in compliance with the terms of this Agreement. This license begins with your first use of the Software and ends 1) as of the duration or date specified in the documentation accompanying the Software or 2) when the Software automatically disables itself. Unless Instantiations specifies in the documentation accompanying the Software that you may retain the Software (in which case, an additional charge may apply), you will destroy the Software and all copies made of it within ten days of when this license ends.

Time bombed evals, how very 1990's of them. I could be wrong about this; it's not completely clear to me whether the evals are time bombed or not (anyone there care to clarify?), or what the term is if they are. Time bombed evals are a really bad idea, which is why we don't use them. It takes time to evaluate something as large as a set of development and deployment tools - we've had more than one customer who's evaluation term lasted from the time of download until the point of deployment - at which time they bought an appropriate license from us.

If we had used time bombed evals, we would have lost those sales - there's no doubt about it. So, if you want to do a full evaluation of a professional Smalltalk environment, there's now only one place to go - here.
