Can I verify signatures without writing files?

I'm finding that if DATA is a data file and SIG is a detached
signature, I cannot verify the signature without refering to one of
these as a file in the filesystem.

gpg --verify sig data # OK
cat sig | gpg --verify data # OK
cat sig | gpg --verify - data # OK
cat sig data | gpg --verify # Nope
cat sig data | gpg --verify - # Nope
cat sig data | gpg --verify - # Nope
cat sig data | gpg --verify - - # Nope

Thots?

No dice. I suspect the problem is that it doesn't know where the data
to verify begins. The signature data is fine because it is
packetized.

Thanks though.
