It seems to me that with openwrt you can do a lot.
This is unbelievable, there are a lot of packages, servers, sip servers, etc
Has up to Tesseract OCR recognition
I have a router with 128Mb I can not do much.
I've looked at the docu and I don't see where it explains if you can put OpenWrt in a barebone with two network cards.
Can you put OpenWrt in a host?
