Bill, at Sugar Labs we are working on taking the olpc server technologies beyond the xs:) We would greatly appreciate your help. I have forward this message to Iaep. A good place to start contributing is http://sugarlabs.org/go/DeploymentTeamthe deployment team is doing some good work with small scale deployments. thanks david As I see it, at this point an XS provides: 1. XO backup service (ds-backup) 2. Activation service? (probably not needed since XOs will be G1G1) 3. Support for 20 networked XOs (ejabberd?) 4. Moodle server (not clear what this means in terms of funcionallity) Is that correct? Is much going to change by January?

Another issue is that reusing available resources (pre-existing wired/wireless hardware, dhcp/dns/web proxy/filtering services) would be very helpful. Even if pre-existing services are inferior to what an XS might provide, for political reasons in a small deployment, it is probably better fit into a framework with which local IT personnel are comfortable. Unfortunately, my impression is that the current XS images are somewhat brittle in terms of assuming they control all of the networking services and as well as requiring specific IP numbering of various interfaces, control of DNS/DHCP/NAT routing/etc. I understand the need to provide turn-key software for locations where there isn't anyone who understands networking. However, I find myself in the situation where even though I know about netmasks, DNS A records, etc.; I have no idea how much of the higher level infrastructure on the XS requires leaving things as they are. For example, can I have an XS with a single Ethernet interface? I think I saw something in a config file somewhere that suggested this (doing DHCP on the Internet facing interface), but I can't find any mention of this anywhere on the wiki. What if I want DHCP/DNS to be handled by something other then the XS, but do what the other services? Given the rapid pace of development, it's hard to tell from the wiki pages what works/used to work/was never implemented/is an idea for the future/etc. I apologize if the above is confused/confusing. Unfortunately, that's the way I feel at this point. I've got this big ball of string I'm trying to untangle and I have no idea where to start. Any suggestions how to get a handle on this would be greatly appreciated.
