Will this old laptop handle a 60Mb VPN?

Yes, interesting isn't it. Fundamentally almost all SOHO routers use a VLAN capable switch chip internally. To get them talking VLANs externally should be a software exercise only but it's often not that straight forward. This also has implications for their throughput. Usually at least one port is directly connected to the CPU and all the others are in fact switch ports. The best throughput can be obtained using only one switch port.

Actually - It was you who mentioned this to someone else earlier (much earlier) and got me to take at look at that.  Before that, I was considering trying to use DDWRT for VLAN, but then decided its probably a pain and perhaps not great solution.
