Symantec owns Thawte which owns 1.3.101. We're happy to donate a reasonable
number of OIDs under this arc for your purposes. Please let me know if you'd
like to take us up on the offer. Thanks to Rob Stradling for bringing this
to my attention.

I'll donate a short OID to the cause if that will help move things forward.
We have the 1.3.187 arc which is only three bytes DER.  If someone has a
smaller arc (third node would be 127 or lower) and would offer an OID from
their arc we can shave off another couple of bytes.
