This is actually the kind of hardware for which Linrad was
designed in the first place. Somehow it should be possible
to implement the drive routines necessary into Linrad, I may
need some help but there should not be any serious problems.
I was looking at this kind of solution before starting to
develop the WSE converters but I found I do not have the skils
for a project like that.

The http://comsec.com/wiki?UniversalSoftwareRadioPeripheral
will perhaps not have adequate dynamic range in all situations,
it may need rather narrow roofing filters, but A/D converters
will surely continue to improve:-)

I think the WSE converters will be unbeaten for quite some time
but in most situations they have more dynamic range than actually 

GnuRadio has a team behind it and maybe they will incorporate
the functionalities of Linrad into it some day. I would welcome 
it if it happens. If it can be done without loss of performance 
I will drop Linrad and work with GnuRadio instead. My interest
is in the algorithms, I am sure others can make easier to maintain
