Yup; playing a bit here with a modded TP-Link 710N (Atheros AR9331@400Mhz - MIPS 24Kc V7.4) mostly such that I can play with OpenWRT. Build is for GSM modems and such.
Found a Uboot modification which provides a bit more stuff.
The most important change is an inclusion of a web server, based on uIP 0.9 TCP/IP stack. It allows to upgrade firmware, U-Boot and ART (Atheros Radio Test) images, directly from your web browser, without need to access serial console and running a TFTP server. You can find similar firmware recovery mode, also based on uIP 0.9 TCP/IP stack, in D-Link routers.
This specific build has added:
- sharing USB storage
- media server
- wan manager (load balancing and failover for multiple WAN connections)
- OpenVPN
- bandwidth monitoring
- custom AT commands (for modems)
- Signal and cell tower information
- SMS Messaging
- modem support and information

Relating to the Almond Plus you could do a failover to a 3G/4G connection if primary WAN fails with this build.
Amazing tiny microrouter.
Connected a Digi 7 port USB hub and a couple of devices to the hub.
