Hi all,
i'd like to introduce myself as a new member to this list.
I'm reading about how to gain new users of Scipy - well, let me be the 
example of one. I'm personally using numarrays for audio work in 
real-time systems such as Pure Data and Max/MSP.
I'm the author of an extension object connecting Python scriptability to 
these systems (http://grrrr.org/ext/py) - numarray support for audio 
processing is thus just a logical thing.

As an unexperienced user i'm currently concerned about two things:
- the dilemma/convergence of Numeric and numarrays: when writing new 
ufuncs for numarrays will i be able to use them without much work in 
Numeric3, in case that's the future?
- the lack of SIMD support for ufuncs: i'm used to the power of SSE and 
Altivec and browsing through the ufunc code of numarrays, i don't see 
any implementation of that. For my applications, this is pretty much a 
must - is it possible to implement SIMD support in the current system 
design and how will custom-made ufuncs be able to profit from that?

best greetings,
Thomas
