I don't think that it's so expensive. Those chips cost almost nothing:
- A good usb/rs232 converter for ~5eur with tax.
- You can rip out the internals of a simple SD card reader for ~6,5eur
or even less.
- The wifi stuff you can yse unmodified. It's on you, which one you buy...
- Some MCU for 2-10eur where you can have SPI or whatever other fancy
stuff you want
Then get a hub chip, make some PCB and nice box for it... It can be done
and the components are not expensive. But it's not for everybody and
takes some time to make it working and look somehow at the same time.
Well, it there will be something like that on the market, I'll buy one.
If not, I'll make one and maybe publish some docs/howtos..
