Good Evening All
The 'easiest' way to check if a route will have non DLS dependencies is to download the route first, then stop all subsequent downloads temporarily. Now go to the tab marked 'today', and locate the route, then right click and go to 'view dependencies'. If the route has dependencies that have an unknown location, then it's unlikely they are on the DLS. In this case, simply delete the route.
If it's a small number, it may be worthwhile double checking if they are listed on the DLS website (
http://www.auran.com/TRS2004/DLS.php ), as CM can sometimes miss the odd dependency as being on the DLS...
As to redistributing other people's content, it comes down to simply copyright laws. Most country's laws will protect the author from unauthorized redistribution. Just because the content is free, doesn't mean it's free for you to redistribute. Note, if you do wish to redistribute content, simply contact the author. They may allow it, or they may not. Some author's also include a redistribution section in their content's license
Also, with the large assets. There's another consideration here. Where one tree may be 100+MB, this tree may contain the mesh (and possibly a texture or two) for other tree assets. This can be useful where the trees have common textures (e.g. if you have 5 trees with the same textures /except/ the leaves). You end up with 1 large asset, and 4 minute assets (generally config and thumbnail only!). This actually saves size, but you do end up with some very large files. Same can go for other things (e.g. my current semaphore signal project has a 46MB mesh library, and 102 'signal' assets that are around 120kb; if you only use 1 signal you end up with a large download, but if you use 20 you have quite a big saving
).
That said, it would be preferred to keep file sizes in mind and re-use assets where possible. However, our computer's can handle quite a large variety of assets these days. And this does also improve the visuals in-game. Instead of having 5 identical trees all lined up, the 5 all look different, as they would in nature. Mind you, you definitely need to find a balance in your scene. However, across a large route, a large number of assets is entirely possible and quite likely.

This is why we introduced the new DLC system, to make releasing payware add-on routes easier
Settle & Carlisle, Murchison 2, Classic Cabon City; they're the first (transferred from earlier add-on releases). We do hope to have more added over time, however these will only be available via the new DLC system. We will be working with the creators, where possible, to help ensure that performance remains satisfactory, depending of course on your detail settings...
