I guess I wan't clear either. I would avoid RPC unless you need to run arbitrary code on the far side. The examples you gave (code to communicate w/ routers, switches, etc. to copy configuration files, check device status, etc.) can be done without needing to send code to be executed or to request arbitrary execution.

That's the thing - there will be some need to execute commands on the router end. i know i'll need to perform a 'writemem' to get the newly copied config written on the router, not just in memory.

I don't particularly like the need for RPC-type commands, but it's there. . .

and the advice is still good. SNMP-based communication is easier than dealing with things like Open3 and Expect. . .
