First of all, about iOS/Android: I think it depends. Here everybody uses iOS. I really don't know any photographer or creative person who uses Android. To me it does't matter, iOS just works beautifully.
As of today, yes it's possible to share! And very simple and exactly what you want (I think).
Go to Adobe Lightroom and login. Then open a Lightroom Collection there. On the top-left you see a share icon, click it and select Sharing Options.
Click it and then you have all the options. Default is Private selected. When you select Limited Public, only people with the link can watch them. Try it!
Thanks for you feedback on using the web interface with screenshots no less! Will have to give it a test-whirl.
LOL on your IOS comment. I know that is the perception that "everyone" creative uses IOS. However I am absolutely certain that there are some creatives in the 50+% of the market that uses android.
So anyway, you now know 2 photographers (one of my friends also is the same) that use Android for their primary phone OS and windows for their desktop OS! Now perhaps they might use an ipad for web browsing too, but we need the mobile software to be agnostic.
Also I realized the subject should point to lightroom.adobe.com. Sorry about that, can't change now.
I fixed the title for you
