I discovered that the MIPS architecture is widely licensed and used

router, hardware version C, uses a System on a Chip with the MIPS
instruction set, FLASH, and RAM. Lots of flash and ram, like 16Mb RAM
and 4Mb Flash (various posts cite different numbers).
I've often thought about buying some of these devices just to have a working platform. If you buy all that stuff separately, it would cost you a fortune. Those people hacking those devices are pretty crazy in their reverse engineering skills.
Yeah 16mb of ram and 4mb of flash is a lot of memory. However, if you compare it to today's serious routers(anything even remotely close to the OP's idea), it's not nearly enough. I just recently fitted a Cisco with 64MB flash and 256MB DRAM. It doesn't have the most complete feature set either...... and if you look at Cisco's memory roadmap, it will probably need upgraded by 2009. And this was in a router designed to handle T3 speeds. 45mbps.
