Well, whoever I end up hiring for this position will definitely be able to persuade me which is the best route to go ACS4.2 or OpenACS.
Again, i'm open to both. If OpenACS, even in it's Alpha stage really IS equal (or better) than ACS, then It's easy enough to adjust to that path.
One of the big positives about ACS in general has been the excellent, and high caliber, community around it.
Thanks,
