Vittore BARONI (I): - As the saying goes, the human mind has no limits.
Lilian A. BELL (USA): - Anything can be installed - that is the magic of the installation!
Derek Michael BESANT (CDN/MEX): - No, because imagination fills the space where possibility might fall away.
David BORAWSKI (USA): - Honesty.
Dmitry BULATOV (RUS): - Any object or idea can be installed with the help of sign substitutes; everything can be such a substitute.
Monty CANTSIN (CDN): - Yes, the orgasmic machine of Neoism?!
Patricia COLLINS (GB): - A black hole.
Billy X. CURMANO (USA): - If there is any idea that can not be installed, I haven't thought of it.
H. R. FRICKER (CH): - For myself there are ethical boundaries.
György GALÁNTAI (H): - “Science, art and politics, if once congregated into a unified reading, can gather unsuspected things out of the world and out of us.” (Vilém Flusser)
Klaus HEID (D): - Love.
Péter KECSKÉS (H): - Transfigurative transsubstantionalised transmutations of transcendent/transcendental essences could not be transferred.
Miroslav KLIVAR (CZ): - No, such an idea does not exist.
Július KOLLER (SK): - Perhaps metaphysical, supernatural, non-anthropocentric phenomenons. But it is the question of time-space. What is impossible today will be normal tomorrow.

Peter NETMAIL (D): - The absence of art.
Jean-François ROBIC (F): - All what is beyond the Earth's dimensions could not be installed, at the moment. (Piero Manzoni's “World pedestal”, but is it an installation?). Auschwitz and Hiroshima can't be installed.
Péter RÓNAI (SK): - I declare with the reminiscence of Wölflin's rudiments of art, that everything carries the possibility of being installed! Turning back the materialization of the idea I ask the question: who could- and how could they install the idea of the installation?
Rod SUMMERS (NL): - Well, I was thinking of putting a sweet-shop on Mars, a brothel on Venus, a thermometer on Mercury, a swimming pool on Neptune, a hound on Pluto!
W. Mark SUTHERLAND (CDN): - God!
László ÚJVÁROSSY (RO): - Time, light and soul; only the traps of these could be installed.
