Sounds like good news, KLS

Hopefully once it is figured out, we can get Rogean to patch the Login Server to work with the new clients as well. Or, do you have access to the Public Login Server host to do it yourself? I forget if Rogean ever gave access to anyone else yet or if it is still just him with access to it.
Thanks for the info, Oscargrouch. The OP_SendLoginInfo has nothing to do with why we can't get into the Login Server as far as I know, though. That packet is for logging into the actual servers once you get into the server list. At this point, we can't even get to the server list yet, but it seems like it won't be that much longer before we can. Once we can, I can get the rest of the opcodes up to date for SoD in a few hours. Then, it will just be a matter of adjusting a few structs and looking for any issues with other structs or encodes/decodes. I don't suspect this will be very hard at all.
Also, I am sure you are referencing the ShowEQ website/svn to get the opcodes and structs. I already mentioned that is where I plan to get the structs from that we will need (or at very least the correct packet sizes). They may have some opcodes we could use there, but as I already said, opcodes are not an issue at all. Plus, the ShowEQ team only cares about having a very limited number of accurate Opcodes, so there are hundreds that would be missing if we only used what they have as a reference. Still great info there though.
As for working with Underfoot, I am sure it probably wouldn't be that much off from what SoD is. So, if SoD is easy to get going, I may even give a shot at Underfoot once SoD is all situated. I don't want to get ahead of myself here, but the change to the LS for SoD should make it work with Underfoot as well, then it would again just be an easy opcode update and a few packet structs again and it would be working. Focusing on SoD solely for now, but just throwing that out there as a possibility sometime. It will probably be $39.99 until the next expansion comes out, so most people probably wouldn't get it anyway.
