Can the connection between LSDS and LSCS use SSL (https)?
Along the same lines - how about IDOL in general? Can IDOL be setup to respond through an encrypted tunnel?
Yes, but you'll have to build your own client using a library like commons-http. The OOTB lscsclient.jar doesn't support that.

Technically, the data stream between LSCS and IDOL already encrypts the data stream, though I'm not sure if it's sent over SSL/https. But yeah, "full" IDOL does have that capability.
