We hope to start indiegogo in a couple of weeks, this means that very probably we cannot start production in dicember 2014, but at beginning of 2015 :-(
We tested CUBIAN X-1 (the version without GUI) and it works well, all devices pops ups immediately (but it is necessary install the non-free firmware with 'apt-get install firmware-ralink').
CUBIAN works well on uSD but in our pre-production pieces we added a SATA HDD 2.5'' and moved the OS on disk using the script.
Chipset wireless is TR5370, 54Mb/s. Last test report 2.6MB/s using ftp on wireless, it is "G". External antennas are included in the price.
The price: 79Euro (no wireless), 89Euro (one wireless) or 99Euro (two wireless).
To make it easy, on Indiegogo we will offer only 2-wireless version, but if you are fast to order, you can pay it only 33 or 66 Euro.
In general, you can ask to have version with no or with one wireless in function of your need.
Ah, yes: PremoBoard is designed to plug on cubieboard face-to-face or back-to-back, it means that one cubieboard can carry 2 premobaord at the same time (one face, one back) for a total of 5LAN, 4WIFI, 9USB: we don't know who can need all these ports, but it is possible to have.
Last, i don't understand the sentence "Actually I would want an FXS port as well" because i don't know what do you mean with "FXS".
