No, I don't have any idea how much effort it will take. What I do know is that the end result is brilliant. And that's what us three think should be replicated to Litecoin.
I'm fully aware that such decision is not mine to make, but I don't think I should shy away from highlighting where else BitMinter would be much appreciated.
I understand what you are wanting, and think it will be better than sliced cheese. I can't make that decision either, that is all up to the great and powerful Doc.
If you want scrypt, and sha-256 multipool is your place.
What aggravates me is when someone comes along and has this awesome idea and thinks it can be done with no problems.
Let's tackle this.
1. Scrypt vs SHA-256
People who mine with GPU, no problem they can do both. What about the majority who mine with asic, what are you going to do with them. ASIC cannot do scrypt, don't ask it to, it can't. That is like asking your Commodore 64 to run Windows 7, it just isn't going to happen. Now, say he adds scrypt support, now he has to add it to the program, but wait, now he has to add checks into the code to figure out if you can handle scrypt, if not then it is only sha-256 for you. Also, you can't merge mine scrypt and sha-256, so it is one or the other.
2. Backend servers.
If you have never been an admin for any major server system then you will never understand the headache that comes with this. This isn't just running XP with bitcoin-qt in the background. No, this is a linux server for reliability. Would I trust Windows Server to this task, hell no. So, most good admins will have dedicated servers, and most likely they run in a vm of some sort for cost savings. Now if he brings on scrypt he will need to add another server at each location to the mix to dedicate for scrypt backend.
3. Website compatibilities.
We don't all use FrontPage for our mainstream sites. Now it looks like he uses liftweb to author his site, but someone still has to re-code a majority of the templates to add scrypt functionality. That also brings back to the servers, the servers have to be able to send sql data for the site to be used, and convert some of the data to json for the api.
Alot has to go into this for someone who I would imaging has a day job and does this on the side.
I am an admin, so that is why this sounds like it sounds. I'm the guy that cringes when he gets called for support because of something incredibly stupid, or has to replace a power adapter because "my dog chewed it again."
If you want to be on a pool that has both scrypt and sha-256, multipool.us is where to go. Multipool has some nice features, but you will need to setup your mining program to use it.
All the best,
