Has anyone found a good way to communicate with a CORBA server using LabVIEW?

We started using a product called COMet from Iona that acts as a COM (ActiveX) to CORBA bridge, but unfortunately a quirk in the LabVIEW ActiveX interface prevented it from working. At this point it looks like we will need to create an interface DLL in C/C++ and call that from LabVIEW, but we would prefer to use a more direct method if one exists. Any ideas?

I need to continuously sample one analog voltage at 1.25 megasamples/second, 16 bits. I'm considering the NI PCI-6251 card in a desktop computer vs. a USB-6251 BNC with a notebook computer. My question is, are there any issues with the USB version keeping up with continuous sampling and data moving at that rate robustly? And are there any issues or problems at all with using the USB product instead of the PCI card product?

Thank you very much for your advice on this!

NI states that "high-speed USB M Series devices deliver bidirectional streaming at up to 1.25 MS/s for analog input" (see http://zone.ni.com/devzone/cda/tut/p/id/4473#toc2).

Also, this article (http://zone.ni.com/devzone/cda/tut/p/id/3705) indicates that the USB signal streaming technology used in the USB-6251 should be able to stream data over USB at up to 3.2MS/s so the speed of the USB-6251 doesn't appear to be limited by the USB interface.
