Is this to be a dividend-paying asset?
If not, I do not see anything other than possibly the limitations of the trading platform that makes it anything more to do with litecoin than with any other asset, be it bitcoin or fiat or icecreamcones or packages of chewing gum or grams of gold or devcoins or groupcoins or whatever.
Once someone has some of these grams of silver, why should they not be free to sell them for devcoins, or groupcoins, or bitcoins, or anything else they would like to buy with them?
Possibly you are letting the tunnel-vision of some existing trading platforms blind you? A general purpose platform such as Open Transactions for example has no prejudice as to which two assets users can choose to trade, among all assets that the server has contracts for...

This is not a dividend paying asset, as I'm not making any trades between the Silver and USD with the investors money. No weekly gains, except when the value of silver goes up, and no losses, except for when the value goes down.
This asset helps LTC by basically providing something to do with them. When you can't do anything with a coin, its not worth anything, so by being able to buy shares in Physical silver, not only are you guaranteeing you LTC will be worth something, but you are still playing the market, but instead of BTC:LTC or LTC:USD, you are playing the LTC:Silver market. If ice cream cones had a definite value, and I could resell them based on stock market prices, I suppose I could make an asset for them too.
Why aren't you free to sell them for devcoins, groupcoins, or bitcoins? Well, I suppose you can if you want, just not through the LTC-Global exchange. Just like you can't trade for devcoins, or groupcoins (what are groupcoins?) on GLBSE. I could come up with many practical uses
1. Shorting LTC, if you don't think LTC will hold its value, buy something that will. (see current silver trends)
2. Increasing the value of LTC, like I said, if you can't do anything with LTC, they are worthless
3. Buying Silver, buy the shares and cash out if you really want to, I'll send the physical silver to your house, and you can sell that physical silver for Devcoins if it floats your boat.
4. Use it as collateral as a loan, I just started seeing people using BTC collateral for loans, so I don't see why it wouldn't work for LTC. If you wanted a BTC or LTC loan, offer to let the other person hold your shares as collateral. Its the same concept if you went into a bank and listed your silver assets as collateral.
5. Just play the market, if you want to make more LTC, just buy the silver on its low days, and sell on its high days, and make yourself some LTC.
And so I ask, if someone wants devcoins or whatever other coin they want, why not just exchange your litecoins for them? If you really want, go ask GLBSE to offer BTC/LTC/DVC/NMC/SC acceptance, and I'll list my asset there. Also, I suppose the fact that I don't use any other coins besides Litecoins and Bitcoins has something to do with it, but the main point is, why should I or any exchange accept coins they don't want to? I honestly don't value Devcoins at anything. If someone wanted to transfer me 100 Million Devcoins, I don't think I would care too much, unless if I could exchange them for BTC.
