semi-relevant: router/server serial console access aggregator

Hi, I am looking for recommendations on a small "footprint" (1U) device that is directly accessible via ethernet/IP and dial-in. It will be hosted in a remote data center to access the consoles of several cisco routers and UNIX servers remotely. I have a feeling somebody has built a cheap and reliable linux/bsd/unix based device with sshd, ethernet port and 8 or 16 serial ports. Please send your replies privately. I will post a summary if there is interest. Thanks.
