Multisite on Rackspace Cloud Sites with multiple SSL certificates

Hi Everyone,

I have been working with WP for a few years( mainly as a designer, but some dev) but I just got started doing multisite.

Questions:

1.) I have the main WP multisite install on rackspace cloud sites ( per client request ) is this something that will cause problems down the road?

2.) We want to install multiple SSL certs on different domains we want to map. Is this possible on top of the dedicated IP address needed for multisite? Each SSL cert has already been purchased, so at the moment I don't believe it is an option to get a wildcard cert.

3.) Any best practices or recommendations for doing this on rackspace or is a different host recommended for multisite?

Thank you!
