I have 10 layer 3 switches including a Catalyst 6500 connecting as a ring topology. It is currently at layer 2 (except the 6500) and I am planning to make it all layer 3 to avoid the RSTP distance limitation. Has anybody  done this type of design? Thanks

No big mystery about it. If you will use L3 topology (EIGRP as you suggested previously), you create dynamic routing and it just works. However, utilization of the links can be a big issue. Just imagine what will happen if one link gets broken. Devices in the middle of the previously ring network, most likely,  will be overloaded, that's why I suggested change of topology.
