The web interface doesn't grow too much because almost all devices use the same page. For example, there is only 1 "Lights" page, no matter what type of light system you have. That's the overall goal of DCE -- to make a common set of commands that devices implement so they are effectively plug and play. I can add X10 devices, adn then a new device driver for Lutron, but without adding an extra page. When we need an extra page, such as some special pages that are unique to the EIB devices, then those pages appear in the Pluto Admin site only if you have devices that require them (defined in the PageSetup table). That way the Pluto Admin site doesn't grow too big.
There is no password for root on the mysql databases. They are set to only allow connections from the core and m/d though. So, from the core, you can run mysql, then do a: grant all privileges on * to 'myusername'@'192.168.%.%' identified by 'mypassword'
That will create a user account with that password, accessible by all 192.168.* machines.
On the Wizard / Devices / Core, you should just be able to check the box for 'analog capture card'. That will add the device for you as a child of the core. In the case of a hybrid, the hybrid m/d is treated as a device within a device (that way all m/d's appear the same), so you optionally could create the device by hand as a child of either the core or the embedded hybrid m/d. Either way, the device driver will get spawned in a screen session at startup by the Start_LocalDevices script.
I replied to the motion list separately. You can IM me any time at: aaronbaalbergen (Yahoo). We have a bunch of programmers who all have different responsibilities. YOu can also IM gheorghiud (also Yahoo) who is in charge of responding to users on the forum. He's not a programmer, but he can direct you to the right one for any particular question.
