[PD] PDa and PDA audio

Thanks everybody for your suggestions and comments on this PDA thread. I 
think there were a lot of folks on the list that didn't even *know* that 
PD runs on PDAs, so that was a nice side effect ;-)

A few of you mentioned that PD might be "overkill" for the simple 
purpose of recording and tagging soundfiles. This is true, but my final 
idea depends on a certain amount of processing [not necessarily 
realtime] to be done to the sound recorded. In the end, I want my PDA to 
generate small algorithmic "compositions" using soundfiles it gathers.

So, a few more questions in this vein, if you don't mind:

1) If I decide not to use PD, is there another fairly full-featured 
recording and processing program that takes command-line arguments and 
also runs on PDAs? I am thinking of Ecasound in particular, but I don't 
know how much modification of the program is necessary to run it on a 
PDA processor.

2) Does anybody know of a PDA-linux-audio specific site, forum, board or 

3) In PD, I assume that writing a sound to file is less prone to 
clicks-and-cuts on a minimal system such as a PDA than playing to DAC. 
Is this correct?

4) Guenter mentioned that max soundfile array size in PDa is 8 secs. 
Does that only has to do with arrays which are being accessed? Or is 
that the max size that PDa can write to "disk" [i.e. Smart Flash memory] 
as well [also in a non-realtime situation]?

5) Any idea if things like LADSPA plugins work on a PDA? [Also in 
non-realtime mode.]
