Is this actually a problem that&#x27;s really crying out for a solution?  I mean, I can&#x27;t say I do collaborative remote planning of trips or shopping online very often at all, but on the rare occasions that I have, sending an email or an instant message of some sort with links in it really does mostly seem to do the trick (&quot;Do you prefer &lt;url&gt; or &lt;url&gt;?&quot; - &quot;I like the first one&quot; - &quot;Great, I&#x27;ll buy that, thanks&quot;).
