 achh, whoops, i forgot that thailand is underwater.

 ok i meant: you remember those industrial flea-markets i mentioned 8
months back (ok, allow me to recap: these buildings are 7 storeys
high, about the size of a football pitch per floor, stuffed on each
level with different components.  you want 5,000 NAND ICs? noo
problem, buy them cash, there and then, even go round bargaining one
person against another if you really want to and have the time - very
much like an antiques market in the UK, only 100x bigger).

 add to that the crash in prices caused by the allwinner itself
resulting in mass-cancellation of orders and there's an opportunity to
get ultra-low prices with, it has to be said, a quite random selection
of kit.

 the alternative is that we have someone go over there who has an
edietic memory and can memorise like a hundred datasheets.

 so, bottom line is: can we please go with what they can get hold of,
easily and cheaply for the first lot, and see what happens?
alternatively, if someone knows a simple way for them to identify
correctly really good stuff, please do speak up, so that i can pass it
on.  they _should_ know, but it's worth checking.
