I have a 1751 trunked to my c2924XL running IP/FW/IDS/PLUS/IPSEC/3DES and it only supports dot1q trunking on the 100Mb interface. Works like a champ, though.

That includes both the 1720 and 1750. In these cases, you had to purchase a 2600 with IP Plus, which is an expensive proposition to avoid the necessity of 2 or more E/FE interfaces. I just setup for a client a 1721 router which DOES support both trunking encapsulations and does it with IP only IOS! This is a huge savings over the traditional options for inter-VLAN routing. There are also new 1751 and 1760 models which I believe also support both modes of trunks.

It cannot be trunked with a 261X. You'd need a 262X. If you have to deal with a 2611, your options become much more limited. You could replace the 2611 with a 2620. Or you could get a ethernet module for the 2611. Unfortunately, last time I checked (whish was a couple years ago, given) those ethernet modules came in two models, 1 and 4 port, and cost about $1000 per port. Another option would be to replace the 2611 with a 1750. It's got one fast ethernet port. If this network is as small as it sounds, it'd be a viable option. Oh, and about trunking, the way it works is you define the switch port connected to the router as a trunk. This allows multiple (in your case, all) vlans to use the one port. The router is configured with subinterfaces on the fastethernet port, one for each vlan. The router can then route between these vlans.
