Install Craft in a subfolder of an ee site? I have an ee site which I can't move over to Craft yet (need a commenting plugin) but I need to extend the site quite a bit. I'm thinking of either installing Craft in a subdomain or a subfolder.

In a Friday chat Brandon advised to go with a subdomain, as having Craft in a subfolder of an ee site that I would/might run into session problems.

Is installing Craft into a subfolder of an ee site a complete no no, or are the potential session problems avoidable? Anything else to lookout for?

Thanks for any help.
In additional to the potential session headaches, you'd also have to worry about getting the .htaccess rewrite rules to play together for each installation considering they inherit from any parent folders.
