We use the ShareExtension a lot at work and I can tell you that it is working perfectly with one exception: if you strip away the changeset one of the working copies is using as parent, you will get error messages in this working copy. OTOH, this problem is easily fixed with the debugsetparents and debugrebuildstate commands. I can't see how you will get into this problem with your environment, given that it used CVS before, which had no strip AFAIK.

So if your use-case is having different folders with different versions checked-out, the ShareExtension is what you should look into IMHO.

With local clones, you might get frustrated with your CVS background. A local clone is really a complete copy of your repository in another folder, not only a different working copy of another revision. Mercurial is clever enough to keep space-usage low with such clones, but it is (or is at least designed to be) nevertheless an independent copy. If you commit in a clone, you cannot switch to another clone and simply check that commit out, because you have to push/pull that commit to the clones first. With shared copies, this is not the case. Whatever you do in the repository of a shared copy will affect all other copies as well (besides working-copy operations, of course).
