RPi solution - pro
* more powerful solution (transfer speeds and simultanly users)
* More flexible and easier to extend (with Linux skills)
* In case of problem, just exchange the SD Card (even for different purposes)
RPi solution - contra
* Bad USB-chipset support (some wifi dongles aren't working properly or need more work to get them working)
* Some USB wifi dongles need additional power source
* less portable
* bit more complicated to setup
OpenWRT MR3040 - pro
* easy to setup
* AR71xx based, like MR30xx: sufficant for the most cases
* MR3040 only included battery with lifetime for around 6 hours
OpenWRT MR3040 - contra
* AR71xx based, like MR30xx: bad I/O perfomance for simultanly accessing users
* hard to extend with other software setup
* not so easy to customize
* Reflash can brick the device unrepairly (quite rare, but can be hard to repair anyway)
* No easy multi purpose usage
That are the things which came to my mind quickly.
BTW: I'm using the tiny 256MB device for testing and that is sufficient in most cases.
