I'm also in Rotherhithe, it depends where you are. Salter road's cabinets are getting FTTC (see the spreadsheet linked in the thread).Pull out the bermondsey cabinet rows, put the postcodes into google maps and you get the cab locations and a guesstimation of the houses they serve.
I live near the CW tube station in an older one of the purpose built blocks. I found out that most of the lines the laid into Rotherhithe as part of LDDC in the early 90s were aluminium, not copper (higher attenuation). This was immediately after BT privatised.
As for where we stand on FTTC. I am hoping that BT are going to let the major works near the tube station subside and then upgrade us. There has been and still is a lot of building work going on.
There are or will be a shedload of broadband customers in very dense properties round here, this may be one of the challenges. This might (though I'm not holding my breath) push BT to do FTTP, since many of the properties have cabinets for the buildings electrical and telephone wiring which might be used.
FWIW - I get 3936 kbps / 832 kbps, giving me a 3mbits profile. Line length was (a few years ago) 5.7Km, yet we're about 1.5km from the exchange as the crow fles. I use A&A.
Gotta be patient living round here, it is a central london telecomms blackspot
