I don't have any suggestions for this, but there are numerous plugins which make adding / creating and managing snippets from within Sublime Text... This combined with a bat file and Dropbox is a very easy and efficient way to go. What I mean, is to create a Plugin directory, the structure of one anyways, in Dropbox and a BatFile to create symbolic / hard link in the application data directory of the pc it is installed on... From there, you run it on any computer you newly install Sublime Text on - then you have an easy way to manage your snippets and you can create a plugin folder for each language, or have them all nested within - they should be loaded into memory automatically regardless of the folder as Sublime Text likes to auto-run files in Plugins...
Another option, is to use that in conjunction with any number of those plugins which won't change how you trigger the snippet, the scope they work within, etc...
Another option is my plugin: AcecoolCodeMappingSystem - This is currently unrelated but version 1.0.0 is coming out soon and will include a dynamic paneling system ( which can be used in a window by itself, or in any window you want to use it in ) and will include a snippets category which can be put in any panel. This will list all of the snippets available to you for the current file you're working on and a simple click, or double click ( your choice ) will trigger it, alternatively I may be able to show the hotkeys bound to the snippet for easy remembering and triggering without removing your hand off the keyboard.
My plugin doesn't currently have this support - right now it boils away all of the code except what is deemed important, to create quick-links such as function names, class definitions, notes / tasks lists, and more with plenty of callbacks and mapping capabilities to refine what is looked for so your project can map AccessorFunctions calls into an entry for each function created and more.
I'm also planning on adding support for macros, urls, bookmarks, wikis ( which will be shown via on_hover dialog ) and more.
It may already be on Package Control - I submitted an application. I am also working on Threaded access to prevent locking the UI thread - for some reason the threading system isn't working so I'm going through it all.
