Can I display recent items from installed QuiteRSS on other computers over local network as web page ( i.e 192.168.1.100/recent_news.html ) ?
due to QuiteRSS being a desktop app the usage as a web interface is initially not poossible.
You can always use
Right click on the news -> Open in Browser
to open the news in an external web browser.
If you really want to forward the news content to some website or web app
this can be done but with a big effort.
So what you could do is to generate your own feed from the initial feed website using a generator like f. e. feed43 http://feed43.com/.
