I am on the road right now, so I am not in front of it, but I have the HandyScope HS3 100MHz USB which can run a strip chart recorder for days / years if you like; depending on hard drive space. The strip chart may be only available at lower speeds? I dunno... I can't remember.... but the Handyscope supports both block transfer and streaming transfer over USB last I knew for certain speeds...
They also have exposed functions available in the DLLs that can probably be accessed via standard ActiveX / COM methodologies from any language include VB, C# / C++, PERL (win32 OLE) etc. http://www.tiepie.com/uk/products/External_Instruments/ USB_Oscilloscope/Handyscope_HS3.html Maybe you have seen this one already... I dunno if it could work for you? maybe?
