Ran a Vong squad last night and had Ooglith Masquer on the Felucian Rancor. I didn't see any limitations on the masquer preventing it from being applied to huge characters. Is there a ruling for Ooglith's ability being applied to huge characters?

No errata or change. Ooglith applies to any non-unique ally, so huge Felcor fits this. You could even use this on a non-unique commander if you wanted to.

Or a Droid,
it just doesn't benifit from the CE

Excellent. The look of horror and disbelief when their mandos couldn't shoot it without being adjacent was spectacular.
