Question on secure admin SSL login in relation to Multi-Domain

[EDIT]
Seems like doing ssl for each multi-domain would be a real nightmare, So I think I will pass on that :slight_smile:
Found http://mu.wordpress.org/forums/tags/https seems to have a bunch of threads. I am going to read up there and see if I can figure out something that makes sense while not overly complicating my life further :slight_smile:

Hello,
I am researching adding ssl to our admin dashboard or logins.

Currently we have our sites login links pointing to whatever domain they are at.
So.
http://joe.iblogged.me login url would be
http://joe.iblogged.me/wp-login.php?redirect_to=http://joe.iblogged.me/wp-admin

So I am thinking I could possibly get a wildcard SSL cert for each of my multi domains so admin ssl logins would work.

Or is it possible to have the admin dashboards all on the main site domain?
At a least there login part be SSL?

Anyone have this setup?
Or a suggestion?

Thanks for any input.
Joe
